¿Por qué la huella digital es única en cada persona?

Un nuevo estudio de la Universidad de Edimburgo detectó un patrón que hace única e irrepetibles las huellas dactilares de cada persona. ¿Qué resultados arrojó?

La piel de las palmas de las manos y las plantas de los pies está cubierta de finas crestas paralelas llamadas dermatoglifos que dan forma, entre otras superficies, a las huellas digitales.

Muchas especies trepadoras las poseen porque estos desniveles minúsculos en la piel mejoran el agarre y les ayuda en la discriminación de la textura de aquello que tocan.

Su particular forma exclusiva para cada individuo ha sido siempre una dilema que la ciencia no había podido explicar, pero los científicos han descubierto cómo se forman las huellas.

Según muestra la investigación que es publicó en la revista Cell, las múltiples variables involucradas en el proceso dan lugar a los patrones únicos que se encuentran en cada persona.
